Firstly, are you sure you installed FH+ correctly? There are plenty of tutorials out there to help with that.
Secondly, the FH+ icon does not actually say "FeralHeart+" nor is it the purple paws. This only happens for the shortcut that appears on your desktop. If you go into the folder where you installed FH+ you should see "Exports", "Media", "My_Presets", and a .EXE with the regular FH paws icon that just says "FeralHeart", like the regular one does. But, it runs the FH+ version of the game instead. (I say that because you might be looking for the purple paws and be skipping over this one?)
Thirdly, When it cannot connect to the front servers there is either something wrong with your game, connection or the servers; You may want to ask a admin for some technical assistance with that.
Hope this helped, feel free to send me a PM with any other questions.
